ui: right-align action buttons + pending peer example fixture

Right-align the OpenWebUI + Metrics Dashboard buttons inside the
expanded model card (`justify-end` on the flex row). Matches the
in-card details which are right-aligned by design.

Add a synthetic PENDING peer to the dummy-run fixture so /make dummy-run
shows what a booting model looks like — status: "pending", service:
[], served_model_name carried in labels. Hostname + peer id are
synthetic but realistic; framework_args resembles a 70B vLLM launch.
